Solution

To continuously append newly generated data to the end of a log file you're monitoring using the tail command, you would need to use the '-f' flag. Here's how you can do it:

  1. Open your terminal.
  2. Type the command tail -f /path/to/your/logfile. Replace "/path/to/your/logfile" with the actual path of your log file.
  3. Press Enter.

The '-f' flag stands for 'follow'. This means that the command will keep the file open after reaching the end so it can continue to output any new content that gets added.
